Custom websites.

What struck me about Mathieu is his professionalism and his responsiveness. He supported us at every step and adjusted as our feedback came in, with real flexibility. Rather than a generic demo, he showed real creativity: a fully custom demo that mirrors how we talk with buyers. And instead of a CMS, he gave us access to the code. We update the content ourselves, straight from the Claude app. A real time-saver, and I’m grateful he trained us on the method. A clear website, optimized for search, and full control over our content. The result is beyond my expectations.

At Renardo Tech, we design imaging sensors to diagnose the state of metal structures. A specialized subject we had to make clear and engaging without losing the rigor, all before our upcoming trade shows. Mathieu started with our identity, built from the ground up, then a site that truly carries it: visual codes shaped for us, zero recycled template, a structure built for our field. What struck me was the responsiveness. Site live in under two weeks. Result: we showed up at the shows with a site that stands out. It genuinely builds our credibility, reassures our partners, and today we share our site with pride. That wasn’t the case before.

Before, my site wasn’t converting. Today, I share it with partners and prospects without hesitation. Mathieu delivered a real showcase: a custom page for my equipment, a gallery of past projects, Calendly booking built in. Clients land, see my work, pick their slot. Result: more calls, more signed clients.

Founder, Studio Lumen

I build a reservation confirmation solution for the restaurant industry. Before, I was sending SMS by hand, one by one. A full day went into it. TeneX Studio delivered a turnkey internal web app: automated SMS through the Octopush API, automated email recaps, a dedicated dashboard per restaurant, a database that makes the solution replicable on demand. Result: hours saved every week, zero manual errors, time reinvested into prospecting, with new signed contracts to show for it.

Days before launch, my site wasn’t ready, my questionnaire wasn’t finalized. Mathieu stepped in fast, in a single day: site finished, questionnaire delivered, live straight after. Result: deadline met, launch saved.
